Attack of the Graske was a Doctor Who video game of the interactive movie genre. It premiered on BBC Red Button at the time of the broadcast of TV: The Christmas Invasion. It was later placed on the series 2DVD box set, to be played by home viewers around the world. It also has been converted for play in a web browser, and is, as of January 2016, available on the official BBC Doctor Who website.

Seen as a game, Graske was not actually the first of its kind. Destiny of the Doctors has essentially the same game mechanics. However, this game's independence of platform has given it far more longevity and universality than the earlier Destiny.

After the Doctor drops Rose Tyler off in 1979 to see ABBA, he picks up the Viewer in his TARDIS and goes to stop the Graske. The Viewer helps find a Changeling and a Graske, pilot the TARDIS and get through doors on Griffoth, but the ultimate decision is when a Slitheen escapes. The viewer must choose whether to freeze the station, killing everything inside, or teleport the kidnapped people back to their homes and destroy the Changelings. After the choice is made, the Doctor thanks the Viewer and drops him or her home.

Not every person who worked on this adventure was credited. The absence of a credit for a position doesn't necessarily mean the job wasn't required. The information above is based solely on observations of the actual end credits of the episodes as broadcast, and does not relay information from IMDB or other sources.

Technically, the casting credit on this adventure is "Casting", rather than "Casting Director"

The vortex loop and the vector tracker are TARDIS components which can be operated by the Viewer at home with either the digital remote control or a computer mouse which has been temporarily linked with the sonic screwdriver.

This story immediately followed The Christmas Invasion and was initially only available to subscribers to the BBC Red Button interactive service. Viewers were able to pilot the TARDIS and fight the Graske both on its native world of Griffoth and in VictorianLondon. From Wednesday 18 January 2006, the story was available to access via the BBC website, but only for UK residents. It was subsequently made available to international users of the website as well.

The Doctor mentions that if the viewer switches their television to ITV tonight the galaxy may implode. This is presumably because the BBC and ITV are rival companies. In his eleventh incarnation, he said that ITV had gone off the air in the second Doctor Who Proms, as a result of saving the Royal Albert Hall and the BBC Proms.

Technically, David Tennant is not credited in this episode as "the Doctor". He receives only pre-title billing. This makes this the only Doctor Who television production which does not credit the role of "the Doctor" or "Doctor Who". This includes Mission to the Unknown in which the Doctor doesn't even appear at all.
